Hair-care composition and hair treatment process

ABSTRACT

Cosmetic composition for hair treatment and care containing at least one water-dispersible cationic surfactant, at least one water-soluble quaternized protein and at least one cationic silicone polymer. 
     This composition is a shampoo, a rinsed or non-rinsed lotion, a restructuring composition or a composition for blow-drying, or a composition for permanent-waving, which are in the form of dispersion, gel, or foam. 
     This composition confers advantageous cosmetic characteristics to hair in respect of disentangling, softness, shape-retention, liveliness and the absence of static electricity; it makes hair ends smoother and promotes quicker hair drying.

The present invention relates to new cosmetic compositions for the treatment and care of hair, containing at least one water-dispersible cationic surfactant, at least one water-soluble quaternised protein, and at least one cationic silicone polymer.

It is well known that hair is generally sensitised in various degrees by the action of atmospheric agents and by the action of treatments such as bleaching, permanent-waving and/or dyeing, with the result that hair is frequently difficult to disentangle and to style.

One of the means generally employed for improving the disentangling and the softness of sensitised hair consists in using surfactants of a cationic nature.

However, the use of surfactants of a cationic nature has the disadvantage of making hair heavier and giving it an oily appearance.

This disadvantage is accentuated in the case of fine hair which is lacking in shape-retention, liveliness and bulk.

It has already been proposed elsewhere to improve the disentangling and softness of hair by employing quaternised proteins which do not have the disadvantage of making hair heavier and imparting an oily appearance. However, the disentangling obtained is inferior to that conferred by a cationic surfactant.

Compositions combining a surfactant of a cationic nature with a quaternised protein have also been proposed.

These combinations do not make it possible, however, to obtain the maximum of the properties conferred by the cationic surfactant and the quaternised protein, because in the majority of cases the deposition of the cation retards that of the quaternised protein.

Furthermore, hair-care compositions combining cationic polymers of the type of MERQUAT 100 and 550, ONAMER or quaternised polyvinylpyridines, with cationic silicone polymers of the Amodimethicone type have been proposed in French Patent Application No. 2,463,612 to produce some retention of the cosmetic properties.

However, these compositions still have disadvantages; in particular, they are still do not result in the required disentangling, liveliness and shape-retention.

We have discovered that, by combining in a hair-care cosmetic composition a water-dispersible cationic surfactant with a water-soluble quaternised protein and a cationic silicone polymer, simultaneous deposition of these three components on hair was promoted, thereby providing a cosmetic composition markedly superior to those known hitherto in respect of the properties of disentangling, softness, shape-retention and liveliness. The hair was at the same time light, resilient, shiny and antistatic and its feel and its appearance was very silky.

Compared to the compositions of the prior art, the composition according to the invention permits better treatment of hair ends, that is to say the most sensitised parts; it makes them smoother and easier to gather together in the wet or dry state, contributing to the improvement of the finish of the hairstyle.

Furthermore, and in particular in the case where the hair-care composition according to the invention requires a rinse, it makes hair resilient at the root more quickly and hair dries more quickly.

The present invention provides a cosmetic composition suitable for hair-care which comprises at least one water-dispersible cationic surfactant, at least one water-soluble quaternised protein, and at least one cationic silicone polymer.

The present invention also provides a process of hair treatment comprising applying to hair a suitable quantity of the abovementioned composition.

The cationic surfactants are preferably present in the hair-care composition according to the invention in proportions of from 0.05 to 7%, and more preferably from 0.1 to 3%, by weight of the total weight of the composition.

The water-soluble quaternised proteins are preferably present in the cosmetic hair-care composition according to the invention in proportions of from 0.05 to 7%, and more preferably from 0.1 to 3%, by weight, of the total weight of the composition.

The cosmetic hair-care compositions according to the invention may be in the form of aqueous or aqueous-alcoholic dispersions, thickened or unthickened, cream, gel, aerosol foam or spray.

They may contain, in addition to one or more water-dispersible cationic surfactants, one or more water-soluble quaternised proteins and one or more silicone polymers, adjuvants usually employed in cosmetics, such as perfumes, colorants, preserving agents, sequestering agents, thickeners, emulsifiers, softeners, foam stabilisers, and other adjuvants usually employed in hair-care compositions, depending on the intended application.

When the composition forms a shampoo, generally it also contains one or more anionic, nonionic, amphoteric and/or zwitterionic surfactants, the total surfactant concentration being generally from 3 to 50% and preferably from 3 to 20% by weight of the total weight of the composition.

The composition according to the invention may also be employed in compositions intended for curling hair (permanent waving). The conventional technique of this permanent-waving consists in first applying a composition containing a reducing agent and then, after the hair has, if appropriate, been rinsed, applying a composition containing an oxidising agent. According to the invention, at least one of the two compositions contains the composition as described earlier.

The various hair-care compositions according to the invention are advantageously offered under pressure, in the form of an aerosol can, and are employed in the form of aerosol foam. In this case, they contain one or more gaseous propellants.

The gaseous propellants employed for pressurising the cosmetic formulations are present in proportions which do not exceed 25% and preferably 15% relative to the total weight of the composition. Carbon dioxide, nitrogen, nitrous oxide, volatile hydrocarbons such as butane, isobutane, propane and their mixtures, non-hydrolysable chlorinated and/or fluorinated hydrocarbons such as, for example, those sold under the name FREON by the company DuPont de Nemours, and belonging, in particular, to the groups of fluorochlorohydrocarbons such as dichlorodifluoromethane or Freon 12, dichlorotetrafluoroethane or Freon 114, may be used as gaseous propellant. These propellants may be employed alone or in combination; in particular mention may be made of the Freon mixture 114-12 in proportions ranging from 40:60 to 80:20.

The pH of these compositions may be adjusted with an alkalising or acidifying agent usually employed in the field of cosmetics. The pH is generally from 3 to 10, depending on the intended application. It is adjusted with the aid of alkalising or acidifying agents which are well known in the state of the art.

The invention is best illustrated with the aid of the following non-restrictive examples.
